On Wednesday morning, reporter Alison Parker, 24, and cameraman Adam Ward were filming a feature on tourism at a Virginia shopping plaza on Wednesday when shots were fired.

Williams, 41, was a journalist who was fired from the TV station earlier this year. He crashed his vehicle while trying to flee state troopers. He was later pronounced dead in hospital.

Morgan labelled the attack "disgusting", calling for America to "God's sake, do something about guns".
